Appendix D Site Access & Intersection Investigation

Sight Distance (east) to end of Uhlmanns Road

Due to location of the proposed driveway in relation to the end of constructed road (Uhlmanns Road), sight
distance to the south is clear to the subject site’s existing driveway (approx. 20m from proposed driveway)
that coincides with the end of Uhlmanns Road/road reserve boundary. Sight distance is available from the
proposed new driveway up the existing driveway (ie into private property) – refer Figure 7 and is
considered compliant with AS2890.1 however may not be compliant with IPWEQ – RS056.



Summary of proposed driveway location

Based on the sight distance investigation results summarized in this correspondence, the proposed
driveway location can achieve AS2890.1 sight distance criteria (55m) with minor vegetation clearing, and
also for IPWEA RS-056 sight distance criteria (123m) but with significant vegetation clearing. It should
noted these assessments are for 60km/h speed limit.

It is recommended that any future design or assessments include a speed survey to determine the 85th
percentile speed for the dead-end road. Significant reductions in vegetation clearing may be realized if the
speed limit or 85th percentile speed is less than 60km/h.
